Abstract
The additive described essentially comprises a selected alkoxylated fatty amine or fatty amine derivative and a special metal salt compound, preferably a metal soap. This additive for heavy oils effects a good emulsification or dispersion of asphaltenes and other higher-molecular weight compounds and, in addition, inter alia, increased storage stability, improved pumpability due to decreased viscosity of the oil and longer service lives of the filter systems. In addition, it also effects enhanced combustion of the heavy oils. The effective amount of additive in these oils is 2 to 2000 ppm. The oils described are suitable, in particular, as furnace fuel for industrial plants and power stations and as engine fuel for marine engines.

The additive of the present invention of embodiment 1 to 3 by with component a) and b) mix and prepare (mixing temperature about 20 is to about 60 ℃).According to preferable methods, at first add component a), and under stirring and nitrogen atmosphere, be heated to about 40 to 50 ℃.Under said temperature and nitrogen atmosphere, be stirred into components b then), thus additive of the present invention obtained.If this mixture that the is cooled to room temperature not desirable viscosity of tool and/or observe is separated, these phenomenons can be eliminated by the organic solvent such as the petroleum distillate that add significant quantity so.-test additive of the present invention:
The additive of test implementation example 1 to 3 is to bitum dispersibility and heavy oil combustion
Improvement.In order to test bitum dispersibility, at first prepare asphaltenes
Solution.The solution of-preparation bituminous matter in toluene:
In order to prepare this solution, the Residual oil of asphaltenes is extracted, it is followingly to advance
Row.In first step, the Residual oil that makes about 30 grams in glass beaker is with about
300 milliliters ethyl acetate is mixed.Stirred this mixture 2 hours down at 40 ℃,
Left standstill then 24 hours, and then filtered by the simple bore strainer.In second step
In rapid, filtering residue is put into the conventional extracting cover that is used for Soxhlet extractron
In the pipe, reused about 300 milliliters ethyl acetate extraction about 2 hours, filter cake
In paraffinic hydrocarbons transfer to ethyl acetate mutually in.In third step, by means of about
300 milliliters pentane dissolves resin Composition by Soxhlet extractron equally.So
After, in the 4th step, by means of about 300 milliliters toluene extraction bituminous matter,
Thereby obtain the solution of desirable bituminous matter in toluene.-test additive of the present invention is to the improvement of pitch dispersibility:
Regulation according to ISO10307-1:1993 or ASTM D4370-32 (heat filtering)
Carry out this test.For this reason, at first make the bituminous matter of the about 10 weight % of 30 grams in first
Solution in the benzene mixes with 100 milliliters of pentanes.At room temperature, will be from embodiment
1,2 and 3 700ppm additive stir respectively into three parts of such bituminous matters-
In toluene/pentane solution.Then, according to these the three kinds of tests of described predetermined processing
Solution.The result: additive of the present invention satisfies test.-test additive of the present invention is to the improvement of heavy oil combustion:
According to VDI2066, the regulation of part 1 (VDI is a Verein Deutscher Ingenieure)
Carry out this test, wherein the usage quantity of embodiment 1,2 and 3 additive is
500ppm, 700ppm and 900ppm.The result: additive of the present invention satisfies examination
Test.
The comparative example 1 to 3
In comparative example 1 to 3, only use compound a respectively
1, a
3And b
1These three kinds of testing liquids are carried out the test method identical with embodiments of the invention.
Result: do not have a kind of testing liquid to satisfy the test that bituminous matter is dispersed and incendivity is improved.
Therefore, additive of the present invention has unexpected efficient aspect dispersion of heavy petroleum asphalt matter and the heavy oil combustion; This be by binder component a) and b) wonderful high synergy produce.Because the advantageous effect of this new additive, oil of the present invention have the performance of wishing especially when those use equally especially in full scale plant, power station and heavy-duty ship engine.
